[R] kmeans: how to retrieve clusters

I'd like to classify data with kmeans algorithm. In my case, I should get  2
clusters in output. Here is my data

colCandInd	 colCandMed
1	82	          2950.5	
2	83	         1831.5
3	1192	 2899.0	
4	1193	 2103.5

The first cluster is the two first lines
the 2nd cluster is the two last lines

Here is the code:
x = colCandList$colCandInd
y = colCandList$colCandMed
m = matrix(c(x, y), nrow = length(colCandList$colCandInd), ncol=2)
kres = kmeans(m, 2)

Is there a way to retrieve both clusters in output of the algorithm in order
to process in each cluster ? (I am looking for smthing like kres$clustList
... where I can process each cluster)

kres$cluster did not yield what I expected ...

thanks for your help
